How critical is a Scrum Master?

A Scrum Master is an important role in a Scrum team. He/She is responsible for making sure that the team follows the rules of Scrum and helps to remove any impediments that are in the way of the development.

The scrum master does not have any authority over the team members and does not make decisions on behalf of them. They do not tell them how to do their jobs or how to behave. The team has a say in what happens with their work, but they also have responsibilities as well.

The question is, is a Scrum Master essential for developed teams? The answer to this question varies depending on what type of team you are referring to. If you are referring to a team that has been working together for a long time, then it may not be necessary. However, if you are referring to a newly formed team or one with many members who don’t know each other well, then it would be beneficial to have someone who can help them coordinate as they work together.
